Application filed June 28, 1913.

To all whom it may concern:

Be it known that I, JAMEs E. VAN DE- VENTER, a citizen of the UnitedStates, residing at Anderson, in the county of Madison and State ofIndiana, have invented a new and useful Work-Holder for Sewing-Machines,of which the following is a specification.

The object of my invention is to produce an improvement in that form ofwork holders for sewing machines shown in Patent No. 1,020,581, issuedMarch 19, 1912, to Nellie Van Deventer Smith and myself.

The accompanying drawings illustrate my invention.

Figure l is a side elevation of a sewing machine with my improved workholder in work-holding position; Fig. 2 a perspective view of the bagand sustaining rods; Fig. 3 a side elevation of my improved form ofclamp with the improved adjacent parts; and Fig. 4 a section on line4.4c of Fig. 3.

In the drawings, 10 indicates the workholding bag which is very similarto the bag in our prior patent, with a casing 11 at each end for thereception of one of the two sustaining rods 12, but here each casing 11is provided with an eyelet 13 in the outer side of the casing near oneend and with an eyelet ld which is conveniently formed through bothportions of the casing practically at that end, so that the rod 12 maybe threaded through the main portion of the casing 11 and caused toemerge through the eyelet 13 and the eyelet lt then threaded over theend of the rod 12, thus displacing a portion of the casing laterallyfrom the rod 12 and leaving the rod uncovered for the space between theeyelets 13 and 14 for the reception of my improved clamp through whichthe rod 12 is threaded. This clamp is provided with a pair of eyes 15,15 through which the rod 12 may be threaded and one Specification ofLetters Patent.

Patented May 18, 1915.

Serial No. 776,269.

of these eyes carries a clamping screw 16 which may be driven intoengagement with rod 12 so as to hold it in any adjusted position. Themain body of the clamp is U- shaped and comprises a bottom bar 17, anupright bar 18 and a top bar 19 which is parallel with the bottom bar17, and threaded through the bottom bar 17 is a clamping screw 20 which,in cooperation with the top bar 19, may clamp the work table 21 of thesewing machine 22. By this arrangement, the sustaining rods 12 may beshifted through the eyes 15 and held in any desired adjusted position,without loosening the clamp 17-1819 from the work table, as wasnecessary in the structure shown in the above-mentioned patent.

I claim as my invention:

A work holder comprising a bag of flexible material having two oppositeportions of its mouth formed into casings, each of said casings beingprovided near one end with a pair of eyelets, a rod extending througheach of said casings and through the eyelets and outside of the casingacross the space between the two eyelets, a pair of clamps one for eachrod, each clamp having a guideway for the reception of a rod and fittingover the rod in the space between the two eyelets, a clamping screw forengaging said rod and holding the same in adjusted position in theguideway, and a separate clamping screw independent of the rod and itsclamping means, for clamping the clamp upon a work table.

In witness whereof, I, have hereunto set my hand at Indianapolis,Indiana, this 26th day of June, A. D. one thousand nine hundred andthirteen.
